Modeling Viscoelastic Behavior of Pig’s Skin in the Respect to Its Anisotropy
The purpose of this work was to analyze the influence of different strain levels on the results of fitting the quasi-linear viscoelastic material model to the experimental curves. The stress relaxation test of pig’s skin tissue was realized. Three values of strain levels were set at 5, 10, 15%. The anisotropy of material was taken into account. Correlation coefficients of fitting were evaluated. The study confirmed both the relationship between the level of strain, orientation of specimens and the values of model parameters.
